篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了基于Python+Django实现药品管理系统相关的知识,希望对你有一定的参考价值。

项目编号:BS-Python-001

技术架构:Python+Django

前端:Boostrap

开发工具:IDEA

数据库:sqlite

项目实现的功能:

   用户分三个角色:管理员、仓库管理员、经销商管理员

主要实现的功能包含:药品的进销存操作、客户管理、供应商管理、经营数据统计、数据导出、系统管理等模块

具体功能展示如下:

库存管理

客户管理

供应商管理

经营统计分析

数据导出

系统管理

数据打印

部分核心代码:
